SPRING FOR SPRING-BEARINGS.

T all tri/ion?, t may concern .lle it known that l, 'l`neononn Il. ll'llinnnr, a citizen oi" the United States, residing at Poughkeepsie, county oit Dutchess and State of New York, have invented a new and uset'ul linprovei'nent in Springs -tor Springllearings, ot which the 'following is u tull, clear, and exact descriiition. reference being had to the accompanying drawings, which 'torni a part o-l this speeitication.

illy invention relates to a spring 'for a epi-ing hearing particularly adapted tor separators.

In such apparatus as centrifugal liquid sei'nufators, which necessarily revolve at a high rate et speed, the revolving` spindle is provided with a spring which is inserted between the bearing and the 'trame ot the machine or other outer support.

It is the object of my invent-ion to producs a spring t'or such bearings which will have the following advantages: maximum flexibility, avoidance of rednctifm in the size ot the main body of the spring for the bearing, avoidance oit tendency to rotation oit the spring, and balancing of pressure, o. providing application points for pressure contact at a plurality oi lines in the length ot the Hiring. l accomplish this result by my novel spring in which I provide a plurality of spring fingers projecting at (litten ent points so as to it'orin a plurality ot' lines of Contact between the bearing and its support. .ln the preferred torm said fingers eX tend alternately in opposite directions 'trom the points oit connection, thus 'forming a plurality ot lines oit contact around the spring, between the points oi connectiol'i of the tingers. Preferably l also provide intermedh atc bridge pieces which connect the cylindrical supporting connections. Preferably I also provide solid portions which extend the length of the spring from which the spring fingers proj-ect inwardly or outwardly.

ln the most preferred `torni of my invention, l form the spring tor the spring bearing 'from a sheet oit metal. From this metal I stamp up spring lingers so as to leave a solid continuous cylindrical portion at top and bottom. The spring fingers i project alternately from such top and bottom portion so that the ends of said lingers oit' each set are in linewith each other, but the ends Speccation of Letters Patent.

Application filed October l, 1910.

Patented Aug. 18, 1914.

Serial No. 584,785.

o't' the fingers ot' the two sets are, with respect to each other, out ot' alinement.

l will now describe the embodiments of my invention shown in the accompanying drawings.

ll'igure 1 is a side elevation of an e1nbodi ment ot' my invention. Fig. 2y is a vertical cross section ot same. Fig. Il is a sectional elevation similar to Fig. 2. Fig. 'l is a cross section on line #l--4- olf Fig. il. Fig. 5 is a view sho-wing another iorrn ot embodiment of my spring Ator bearing. Fig. (3 is a View showing another 'torm ot embodiment oi my spring for bearing.

The spring (as shown in Figs. 1+i) is formed from a piece of sheet metal so that it has a continuous cylindrical surface n, a', at top and bottom, which sui-tace is ot somo width, and a width sullicient to produce, by its contact with the bearingsuch triction as to reduce its tendency to rotate and it' at all, to lessen the consequent wear on the bearing. From this metal is stamped up spring fingers c, c', alternately projecting from the upper portion a and the lower por! tion a. On each side of these spring `lingers are metal sections, or bridges, which extend from portion (L to portion fr. In the form shown in F ig. 5 the portion f, corresponding to the portions a and a ot' the embodiment ott F iwi, is continuous not only in length but also in width or height of the spring, and the spring fingers c, c are bent alternately from the upper and lower edges oit said portion f. The form shown in Fig. (i differs from that shown in Fig. 5 in that the springr lingers f', c are connected to the portion by rivets y. ln all these constructions the spring tor the bearing, arf: a whole. does not yield but only the spring fingers, thus maintaining the size oi the spring constant and decreasing the tendency to rotate. Further, the solid portions a, a (Figs. l-ll) and f (Figs. 5 and 6) also assist in preventing rotation and thus avoid cutting and wearing. Again, as may be seen, one set ot lingers extends the same distance and have their points of pressure application on a line, and` the same is true with the other set of lingers, but such points in the two sets are on different lines, hence I have a balancing pressin'e. The spring iingers c, c', as shown, project outwardly and contact with the outer one side of the Center of the ein'iport. merely reversing a'. e. having 4he Sprit {in jers proyeet in\.f'iirdly. the 'seinek rrinne or support.

Hering' nonv fully described niy invention, what i Chinn und desire to protect by Letters Patent is:
